The first three spectral lines of H-atom in the Balmer series are given $\displaystyle \lambda_1, \lambda_2, \lambda_3$ considering the Bohr atomic model, the wave lengths of first and third spectral lines $\displaystyle \left(\frac{\lambda_1}{\lambda_3}\right)$ are related by a factor of approximately '$\displaystyle x$' $\displaystyle \times 10^{-1}$. The value of $\displaystyle x$, to the nearest integer, is \_\_\_\_.
